> I observe that people aren't scared enough to take action. They continue to dance around the issue in political euphoria. The changes to our lifestyle are happening too slowly to be effective.
These are all reasonable observations, but they don't remotely substantiate "The chances of humanity surviving are incredibly slim, IMO."
Just tone down the hyperbole. No serious informed science exists to predict human extinction, though lots of ecosystems and most large wild animals are at high risk.

The associated period of massive carbon release into the atmosphere has been estimated to have lasted from 20,000 to 50,000 years. The entire warm period lasted for about 200,000 years. Global temperatures increased by 5–8 °C.[21]
The hot-models Sabine referred to are in range of 4.8 - 5.6 if I'm not mistaken...
So, to avoid engaging in a Gish Gallop on this issue, I'm going to ignore the specifics except to point out that neither of those links says anything about human extinction at all.
It is reasonable to be concerned. But deploying easily-refuted hyperbole makes your (our!) cause MORE likely to be ignored as crackpot nonsense, not less.
Do you really mean that humans can survive without ecosystem? Mass extinction events are causing chain reactions ... I do not care about the causes. I'm not a climate activist. I'm just an average guy that can't do a squat and tired to be afraid for my children's future. I just accepted the fact that humanity will destroy itself sooner or later. I do not see any point in expecting wonders.
These are all reasonable observations, but they don't remotely substantiate "The chances of humanity surviving are incredibly slim, IMO."
